I was out this evening and had a pretty neat experience. I had a small 6 push 3 does by me and then out into the field behind me. I could have probably taken him, but chose to let him go. He was grunting the whole way by the stand. Then, about a half hour later, I hear it in the field behind me. I turn around in the tree to see this very same buck and another buck cracking horns! I watched the whole thing for about 10 minutes until dark. They were pushing each other around a bit, but it was mostly sparring off and on.
So yeah, things are starting to boil a bit here.
